Title: Screw tapping machine with shaft frame - has spindle rotated and axially moved via gear drive on drive shaft rotated by power cylinder axial movement
Inventor: EGGER KARL
IPC: B23G3/00
Filed: 1980-05-14
Abstract: The screw tapping mechanism comprises a frame (10) carrying a rotatable drive shaft (22), which receives its input from a double-acting power cylinder (20) etc. to rotate and axially move the spindle (30) carrying the tap. The shaft (22) is not axially movable and carries rollers (24) which engage an internal helix (26) in a bush (14). The latter is axially movable by an actuator (20). The spindle is rotated by the shaft via spur gears (28,30), and the rotation causes its axial movement by an externally screw threaded bush, keyed to its upper end engaging an internally threaded bush (36) held in the frame. These two bushes are preferably interchangeable to accommodate taps with different thread pitches.

Title: Two layer diaphragm for diaphragm valve - has thicker layer weakened in bending to reduce separation tendency
Inventor: MUELLER FRITZ
IPC: F16K7/12
Filed: 1980-05-14
Abstract: A sealing or shut-off diaphragm for a diaphragm valve intended for liquids or gases comprises an elastomer or similar support diaphragm of comparatively large thickness and a much thinner sealing diaphragm, esp. of PTFE, bonded to it. The thick, support diaphargm is weakened in a predetermined region on the side remote from the sealing diaphragm, in order to reduce its resistance to bending. The weakening may be made in the form of a number of depressions on this side, more specifically concentric grooves or a series of blind holes. These grooves or blind holes extend to a distance to 1-1.5mm from the face of the sealing diaphragm. With this arrangement, the tendency of the two diaphragms to shear apart is reduced.

Title: Transporter and cropper for looped rolled rod - where front and tail ends of looped rod are sheared off before rod travels to coiler
Inventor: BERGMANN MANFRED DIPL ING
IPC: B21C47/26
Filed: 1980-11-29
Abstract: A looping machine lays overlapping loops of rod on a conveyor belt. The first loops consist of faulty rod, so the loops are allewed to fall off the conveyor. A swivel platform is then lowered to pick up the first good loop, and has a pair of shear knives which cut off the initial faulty loops. The loops of good rod travel over the platform to a coiler. The final rod loops also consist of faulty material; and a second upper swivel platform, also fitted with a pair of shear knives, is used to pick up the first faulty loop at the rail end of the rod and to shear it off the good loops. In this way, the faulty front and tail ends of rolled rod are easily removed, so only the good portion conforming to the specified dia. reaches the coiler. Automatic removal of faulty front and tail ends of rolled rod prior to coiling is achieved.

Title: Hydraulic control arrangement for two working cylinders
Inventor: RASPER MANFRED
IPC: F15B11/16
Filed: 1981-05-21
Abstract: The hydraulic control arrangement has a pump (10) which serves to supply a single-acting working cylinder (18) and a double-acting working cylinder (32). The control is effected either via a reversing valve (16) and an electromagnetically releasable, pilot-controlled non-return valve (17) or via two of such valves (50, 51; 103, 123), of which each is allocated to a working cylinder. Whereas the pump is switched on to extend both working cylinders and to lower the double-acting one, the single-acting working cylinder is retracted with the pump switched off. As a result, the electromagnetically operable non-return valve (17) is relieved. A control arrangement of this type is especially suitable for actuating liftgates of trucks. <IMAGE>

Title: Noise-reducing drill rod
Inventor: KLUGE GUENTHER DR ING
IPC: E21B17/00
Filed: 1981-06-10
Abstract: The invention relates to an arrangement for reducing the noise during the operation of percussion drilling machines, used in particular in underground mining and tunnelling, by restricting the generation of acoustic vibrations of the drill rod and limiting the emission of mechanical vibration energy from the drill-rod surface. The generation of acoustic vibrations is largely restricted to the shank end of the drill rod by fastening a sleeve-like, metal mass collar and two additional masses held at a defined distance from the mass collar by a sleeve-like plastic element (mass ratio of mass collar to additional mass: about 4:1). The emission of mechanical vibration energy is limited by applying a sequence of four sleeve-like plastic elements each and a sleeve-like metal additional mass following the arrangement described above. The entire damping arrangement covers about one-third to one half of the drill-rod length so that the removal of the drill cuttings is not unreasonably restricted and the increase in weight of the drill rod is kept within limits.

Title: Method and apparatus for determining the relative elongation of rolled strips in relation to the central areas of the strip
Inventor: KUETTNER HEINZ DIPL PHYS DR
IPC: B21B38/02
Filed: 1981-06-19
Abstract: To determine the relative elongation of the edges of rolled strips (1) during transfer in relation to the central areas (4) of the strip, the vertical distance of the edge of the rolled strip (1) from a reference point (X) is periodically measured and the horizontal speed of the rolled strip (1) during the respective measurement is specified. The vertical distances (ZA) and the speeds (v) are stored. The square root of the sum of the differences ( DELTA z<2>) of the squares of the distances and of the product of the associated speed and measurement period ( DELTA t) is calculated for in each case two successive measured values (ZA) for the distance. The square roots are then summated. The ratio between the sum of the products of the measurement periods and speeds (v) and the sum of the square roots is subtracted from one. <IMAGE>
Patent DE-3133656-A1 (DE)
Title: Method and device for the analysis of chemical solutions
Inventor: JOLA MARTIN
IPC: G01N31/16
Filed: 1981-08-26
Abstract: A method for the analysis of chemical solutions is described which comprises adding a defined volume of a reagent (5) for a short period to the sample stream (3) which contains the component in the concentration CA which is to be determined. Since the concentration of the reagent (5) decreases on the one hand due to consumption and, on the other hand, due to being transported away with more sample (3) flowing in, the equivalent point of the reaction is reached after a defined time teq, and this can be measured by means of suitable sensors (11, 12). There is then an unambiguous connection between the equivalent time teq and the concentration CA of the sample (3), so that the concentration CA in the sample (3) can be determined by a measurement of time or signal between the time t0 of the addition and the appearance of the equivalent point Teq. The corresponding device comprises a reaction vessel (1) with an inflow and outflow (2, 4), a metering device (7) for the reagent (5), and sensors (11, 12) with an evaluation instrument (13). <IMAGE>

Title: Integrated semi-conductor memory
Inventor: MUELLER WOLFGANG DR ING
IPC: H01L27/108
Filed: 1981-09-30
Abstract: The invention relates to an integrated, dynamic semi-conductor memory having memory cells which in each case comprise an MIS transistor with a substrate region at floating potential. The substrate region is charged information-dependently by a charge pumping pulse, thereby shifting the turn-on voltage of the MIS transistor. The aim is for a good mutual insulation of the memory cells and simple production of the semi-conductor memory. For this purpose, according to the invention a base substrate (10) of a monolithic semi-conductor body is provided, which contains the substrate regions (5) of the memory cells as superficial subregions, there being provided underneath each substrate region (5) a semi-conductor region (8) connecting the source region (2) to the drain region (3) of the assigned MIS transistor, which semi-conductor region is of the same conduction type as the source region (2) and drain region (3). The field of application comprises dynamic semi-conductor memories of high packing density. <IMAGE>
Patent DE-3140101-A1 (DE)
Title: Press roller
Inventor: SELD SIGURD VON DIPL ING
IPC: B30B9/20
Filed: 1981-10-09
Abstract: In the case of press rollers for chat rollers in the oil mill industry, which press rollers are composed of a hollow operating cylinder and a roller spindle which penetrates the latter, there is a danger that material will be subjected to impermissibly high loads at the points at which the roller spindle emerges from the operating cylinder. These high loads are avoided by means of a design in which the roller spindle (2) does not have any contact with the operating cylinder (1) at the ends of the latter, even when loaded, but in which the operating cylinder (1) and the roller spindle (2) are only connected in a region which is situated some distance from the end faces of the operating cylinder (1). Power is then only transmitted at the connecting points. Two clamping points (3) can advantageously be provided between the roller spindle (2) and the operating cylinder (1), dividing the latter into three approximately equal lengths. <IMAGE>
